It was actually a really easy job the bar didnt have to come off nor did the grille
I bought the biggest unit I could and it fit like a glove
The only thing I had to do was moved the fan cover a little to get the zip tie backs on
I can take more pics if anyone wants
The job took me about 2 hours because I wanted to get it right
As for plumbing you just take the pipe that goes into the passenger side of the radiator run that to the cooler then run a new pipe back to the other end of the the original pipe Therefore you are putting the cooler inline to the radiator
Note when you buy the cooler buy an extra 2m of pipe your going to need it
